2  Allocation of resources over time to accomplish specific tasks.  Scheduling is done in the short term time horizon i.e. months, weeks or days.  Effective and efficient scheduling can be a competitive advantage.

3 Long term Intermetiate term Short term Business Plan Determine the long-term strategies for production and capacity External environment Forecast of demand Strategies and policies Material Requirements Planning (MRP) Determine the needs for components and raw materials Aggregate Plan Determine production capacity Master Production Schedule (MPS) Determine the production schedule for specific products Scheduling Detailed planning of orders Aggregate planning Master scheduling Different Levels of Planning

4 › What is to be done (Work) › When (Timings) › By whom (Workers) › With what equipment. (Work Stations)

5  High Efficiency  Low cost  Low inventories  Good customer service  Meeting Demand on time

6  Scheduling Demand: › Scheduling customers by assigning a specific time for order fulfillment.  Scheduling Workforce: › Scheduling that determines when employees work.  Scheduling Operations: › Scheduling in which jobs are assigned to work stations or employees are assigned to jobs for specific time periods.

7 Forward Scheduling › The scheduler selects a planned order release date and schedules all activities from this point forward in time. › Produces a schedule though it may not meet due date. Backward Scheduling Begins with the due date and schedules the final operation first. Schedule is produced by working backwards though the processes by working backwards though the processes Due Date Now Now

8  LOADING / DISPATCHING: › Involves assigning jobs to work centers and to various machines in the work centers  SEQUENCING: › Sequencing is concerned with determining the order in which jobs are processed

9  Random  FCFS  EDD  SPT (Shortest Processing Time)  LWR (Least work Remaining)  FOR (Fewest operation Remaining)  ST (Slack Time)

10  Gantt charts are named for Henry Gantt, a management pioneer of the early 1900s.  He proposed the use of a visual aid for loading and scheduling operations.  Most commonly used scheduling tool in the world.
